چکیده
The mol-ecule of the title compund, C(30)H(28)N(2)O(2), a Schiff base synthesised via a condensation reaction between 4-meth-oxy-benzaldehyde and 3,3'-dimethyl-benzidine, a crystallographic twofold rotation axis passes through the mid-point of the C-C bond of the biphenyl unit. Thus, the asymmetric unit comprises one half-mol-ecule. In the biphenyl unit, the aromatic rings are twisted by 13.49 (7)° with respect to one another. The dihedral angles between the biphenyl and meth-oxy-benzene rings are 49.95 (12) and 50.06 (12)°. In the crystal, weak inter-molecular C-H⋯ O hydrogen bonds contribute to the stabilization of the packing.

Dedicated to Professor Heribert Offermanns on the occasion of his 75th birthday The title compound (H2tpsac) was synthesized from 6-bromosaccharin and 3,3′′-bis(bromomethyl)-m-terphenyl. The ability of tpsac to serve as a tetradentate bis-bridging ligand was demonstrated by the formation of the dinuclear ruthenium(I,I) complexes [Ru2(CO)5(μ ,μ-tpsac)]2, [Ru2(CO)4(μ ,μ-tpsac)]n, [Ru2(CO)4(PPh3)2...
